Is it cheaper to buy a plane ticket from WBU to San Diego Airport last minute?
Being the spontaneous type is a great way to travel around, but it isn't necessarily the best way to land a bargain plane ticket.

Based on flight pricing and demand studies in 2022, we have found that the best time to book domestic flights is between 28 – 35 days ahead of the departure date, and international flights three to four months in advance. Leave your spontaneous side for when you reach your destination!
